"Banta's faith" joke

Banta was walking in the mountains just enjoying the scenery when he stepped too close to the edge of the mountain and started to fall.
In desperation he reached out and grabbed a limb of a old tree hanging onto the side of the cliff.
Full of fear he assessed his situation. He was about 100 feet down a shear cliff and about 900 feet from the floor of the canyon below. If he should slip again he'd plummet to his death.
Full of fear, Banta cries out, "Help me!" But there was no answer.
Again and again he cried out but to no avail.
Finally Banta yelled, "Is anybody up there? "
A deep voice replied, "Yes, I'm up here."
"Who said that?"
"It's the God."
"Can you help me?"
"Yes, I can help. Have faith in me."
"Help me!"
"Just let go."
Looking around, Banta became full of panic. "What?!?!"
"Have faith in me. Let go. I will catch you."
"Uh... Is there anybody else up there?"
